Stove knobs receive heavy use, so replacing them is a common repair job. Over time the letters and numbers that indicate the heat level rub off and wear away, making it difficult to cook and operate the stove. Grease and residue build up on the underside of knobs, making them turn poorly or not at all. Anyone can replace a stove knob, and if you're careful to choose the correct knob and install it properly, you'll succeed on the first try.

Things you need
- Grease-free lubricant spray
Rotate each knob until it rests in the off position. Smell for gas (if you have a gas stove) to make sure the burners are off. Wave your hand over burners to check for heat if you have an electric stove.
Grip a knob between your fingers around the rim of its base. Pull the knob outward and away from the stove's surface to remove the knob. Repeat for each of the stove's knobs.
Apply a grease-free lubricant to encourage sticky knobs to come free. Remove the lubricant's lid, attach its straw to the hole's nozzle and press down on the nozzle to spray. Direct the straw and spray to the underside of the sticky knob. Allow the lubricant to penetrate the knob for a few moments. Grip the knob and pull outward to remove.
Align a replacement knob's hole with one of the stove's knob stems. Press the knob onto the stem and push until the knob is fully inserted. Repeat for each stove knob.
Test each new knob to ensure that they rotate through the full range of motion allowed by your stove--gas stove knobs must engage the igniter to ignite the pilot lite.
Tips and warnings
- Replacement knobs are available through your stove's manufacturer. Although generic hardware store knobs might fit, they might not match your stove.
- If you smell gas and cannot turn it off, contact emergency services and your utility company.
